The ProOne® G2.0 filter is easy to install, use, and clean. Unlike competitor filters, no priming is required, and no add-on filters are required to remove fluoride. The ProOne® G2.0 filter is silver-infused to prevent the growth of bacteria within the filter itself.

Each container is manufactured from a single piece of stainless steel and sold with a stainless steel spigot (not plastic) for durability.

Already own a competitor’s water filtration system? The ProOne® 9″ G2.0 is designed to work with most other brands of gravity fed water filtration systems which use a 2″ by 9″ filter element. Now you can upgrade to Propur™ filter elements without purchasing an entirely new unit.

Disclaimer: In compliance with state laws of California, Iowa, and Wisconsin, the Propur™ water filtration products are sold and shipped to residents of these three states without any claims except for aesthetics, including chlorine reduction, and improvement with taste, odor and sediment.

More On Independent Test Lab Reports

Propur™ consults with an independent third party certified water testing laboratory offering unbiased analytical testing on the ProOne® G2.0 filter.

The ProOne® G2.0 filter has been tested in accordance with NSF- 42 and 53 standards, and the only “ALL-IN-ONE” CONTAMINANTS & FLUORIDE GRAVITY WATER FILTER that qualifies as a microbiological water purifier by NSF protocol P231.

Test results by Envirotek Laboratories, Inc., certified by the state of New Jersey Department of Environmental Protection show the ProOne® G2.0 filter removes and/or reduces contaminants including heavy metals, VOC’s, monochloramines, pesticides, herbicides, pharmaceutical drugs, fluoride, bacteria, viruses, Giardia and more without the need of any add-on filters. Even the contaminants that were found in the Toledo and West Virginia water supplies are covered by the ProOne® G2.0 filter.

A TDS Meter indicates the Total Dissolved Solids (TDS) of a solution, i.e. the concentration of dissolved solids in it. As dissolved ionized solids such as salts and minerals increase the conductivity of a solution, a TDS meter is able to measure the conductivity of the solution and provide an estimate of the TDS.

A TDS meter typically displays the TDS in parts per million (ppm). For example, a TDS reading of 1 ppm would indicate there is 1 milligram of dissolved solids in each kilogram of water.

TDS is a measure of total dissolved solids and NOT dissolved contaminants. A higher TDS can simply be high calcium or mineral content.

As Propur™ filters are made from minerals, TDS may read higher after the water has been treated. This does not mean the filter isn’t working. Rather it means the TDS meter is picking up the minerals that have been released by the filter. A PPM meter is the same as a TDS meter, it is simply measures dissolved solids in water. A TDS meter is not generally recognized in the industry as a proper means of testing water for contaminants.

TDS meters were created by manufacturers of reverse osmosis systems as a means of demonstrating the effectiveness of reverse osmosis, which removes most, if not all minerals.
